Saucony Endorphin Speed 4

Who Are Saucony Endorphin Speed 4 For?

This is a versatile trainer for runners who like to go fast but want one shoe to cover most of their week — from tempo sessions to race day. It suits intermediate and experienced neutral runners chasing PRs across a range of distances, rather than someone seeking a plush, do-nothing recovery shoe.

Feelings and Experience

The PEBA foam feels soft and lively underfoot, with a springy rebound that rewards a quick, rolling cadence. The winged nylon plate adds snap without the harsh, tippy sensation of a stiff carbon racer, so transitions feel smooth as you accelerate. On very easy shuffles the tall, soft stack can feel slightly floaty, and it comes alive only once you pick up the pace.

Performance Specs

• Drop: 8mm heel-to-toe offset — a moderate slope that eases the calves while still encouraging forward roll

• Cushioning: High, PWRRUN PB (PEBA-based) foam — generous protection that stays resilient over long efforts

• Responsiveness: High — driven by the springy PWRRUN PB foam and a winged nylon (composite) plate

• Stability: Moderate, neutral — the winged plate and contoured base tame the soft stack, but it's not a motion-control shoe

• Pace: Optimal for 3:45–4:45 min/km (6:00–7:40 min/mile)

Best Distances and Maximum Speed

It genuinely excels from the 5K up through the marathon, with the half marathon and honest tempo work as its sweet spot. Push the pace and the foam and plate work best around 3:45–4:15 min/km (6:00–6:50 min/mile), where the rebound is at its liveliest.

Technologies and Materials

The midsole is Saucony's PWRRUN PB, a PEBA-based superfoam, paired with a winged nylon plate for guidance and pop. The breathable engineered mesh upper holds the foot securely for faster efforts. Specific weight and stack height weren't provided here, but expect a light, race-adjacent build typical of the Endorphin Speed line.
